Figure 2. Anesthetic degradation to carbon monoxide at equiminimum alveolar concentrations (1.5 MAC) concentrations by (A) barium hydroxide lime and (B) soda lime. Each data point is the mean +/− SD (n = 3). The single data point at 300 min reflects undetectable carbon monoxide from sevoflurane, methoxyflurane, or halothane.
